Why Trust Wallet compatibility only on macOS 11.0 (M1 chip) ?
Please update so that Trust Wallet can be accessed on MacOS Catalina 10.15. or 10.15.7 or later
because users of MacOS Catalina
version 10.15. or lower version 11.0 (M1 chip) cannot access Trust Wallet 
It’s automatically supported based on current iPhone/iPad version since Trust Wallet does not have fully native macOS app. For now you can only have it accessible from M1 chip.
My iPhone is an older version and Trust Wallet does not support older versions of iPhones,
Hopefully in the future the Trust Wallet team will update so that it can be supported for all iPhone versions
